Description
Technical Field
The invention relates to the field of marine coatings, in particular to a marine coating capable of effectively preventing marine organisms from attaching and a preparation method thereof.
Background
The marine coating is a general name of the coating which is used for various parts of ships and ocean engineering structures and meets the requirements of preventing seawater, ocean atmospheric corrosion, ocean organism adhesion and other special requirements. There are over eight thousand plants and over fifty thousand nine thousand marine animals in each territory of the world, of which there are over six hundred attached plants and over ten thousand attached animals. The larvae or the robes of the attached organisms can float or swim, and after the larvae or the robes develop to a certain stage, the larvae or the robes are attached to objects such as ship bottoms, underwater structures or shore rocks, settle and further propagate. When a large amount of marine organisms are attached to the bottom of the ship, the marine organisms can cause great harm to the ship, so that the marine organisms not only increase the dead weight of the ship and reduce the load of the ship, but also greatly increase the resistance of the ship body, and further reduce the navigational speed of the ship and increase the fuel consumption. Data show that when the ship bottom is seriously polluted, marine organism accumulated chips can reach more than ten centimeters in thickness, the weight of each square meter reaches more than twenty kilograms, and the weight of ships with the ship bottom of nearly ten thousand square meters can be increased by more than two hundred tons.
In marine environments, corrosion damage and biofouling of metal structures can be prevented by coating ships with marine paints, which is the simplest and feasible method. The required ship coating is constructed on the surface of a metal hull of a ship, concrete and other marine structures through simple processes of brushing, spraying, dipping and the like, and forms a tough protective and decorative coating through processes of natural drying, baking, solidification and the like. The marine coating can play a role by forming a sealing effect on the surface of metal or concrete and preventing a protected substrate from directly contacting with a marine corrosive environment, and after the marine coating is coated, the main effect mode of the marine coating embodies value through an interface effect, namely the marine coating has a special interface structure and interface components and can effectively inhibit biological adhesion.
